Claims. (Cl. 100--215) This invention relates to an improved. baling press, and has for one of its principal objects the provision of a device ofthe class described which will be useful in the art of compressing practically any materials vinto a bale, bundle or package in a substantially automatic mechanical or other means.

Another object of the invention isV the provision'. ofv a compressing mechanism for balingl various materials, particularly refuse, paper, or the like in a simple automatic manner, and which will produce. a neat, easily disposed of,l unit, whichv can be of any desired size depending upon requirements, varying from the needs of' the small residence user to the large factoryuser.

A further object of the invention is toprovide. a baling pressor the like, particularly for trash or refuse, wherein large quantities of such material. will` be drasticallyy rcduced lin volume for easier and faster handling.

Yet another object of the invention is the provision of a baling mechanism, wherein raw trash and other 4 refuse would be handled inv a single operation, namely when it is placed in the apparatus of this invention.

Another and still further important object of' the in.-

vention is to enable disposal trucks toy handle `a great deal more of such refuse in a highly eicient and better organizedv manner, thereby reducing theV number of trash pick-ups in any area.

Other and further important objects of the invention will be apparent from the disclosures i-n the accompany- Ving drawings and following specification.

The invention, in a preferredi form, is illustratedin the drawings and hereinafter more fully described.v

As shown in the drawings:

The reference numeral 10 indicates the machine generally having a main frame 11. This main frame 11 is supported upon a base member 12 and includes end walls 13 and longitudinal tie members 14 at the top of 2,873,665 Patented Feb. I7, 1959-.-

2 the main frame 11. Additional. longitudinal, tie-meuk bers 1S are provided aty the middle portion of the: main frame 11 and uprights or columns 16 extend throughout the height of the entire apparatus. These columns are connected by a head member 17 at the top. thereof, and doors 18 form, the two side walls of the lower chamber for final compression of whatever materia-l which is placed in the apparatus. These doors 18 .include reinforcing ribs 18a and are mounted` on hinges'19,v all as best shown. inl Figure 3. Lugs 20. are provided` for shear pins 21 on the doors 18, and additional lugs. 22, which cooperate with the lugs 20, are on the` base 12 (Figure 6). l

The doors 18 are provided with notches 23 .in order to clear the l-ugs 20, al1 asbest shown in Figure 1, Vand hooks 24 are provided for holding theydoors 18 iu open position, see the dotted lines in Figure 3.

The material introduced into the machine is compressed by a ram 25 which is adapted to move from the. full line position shown in Figure 3 to the dotted line posi` tion illustrated in the' same figure. The ram. 25 is pro-.- vided with a ram rod 26 which is: connectedto a piston 27 (Figure l) operating on a cylinder 28 (Figures 2 and 3) which cylinder is supported by a mounting plate' 29 (Figures l and 3). 1 Y

The piston 27, connected by theram; rod 26 tof, the ram 25, is hydraulically operated from: a conventional.

power source 30L (Figure l.) which includesa motor.

30a, a pump 36D, a pressure relief, valve 360,- a. three; position Valve 36d, a reservoir 39e and'. conduits 30.15

It will be understood that the gates 13 areopened to remove compressed material from the device aftery the ram 25 has operated, and when the rai-n.25 is.- hrits; upper-most position, as showny in Figure 3, trash, rubbish; or any other' material tobe compressed can .be'introduced into the space below the 25 through gates,

31 which arev adapted for upand down vertical movement in slots 32 in the walls 15'. The walls 13. are also provided with slots, as shown by the reference'numerals 33 (Figure 7) andv additional` slots 34 are provided in the walls'14 for receptionpf the gates 31 when,y

in their upper position. y.

EachI of the gates 31 is provided with projections 35' (Figure 8), to which cables 36 may be attachedfFigures l and 3). The cables 36 operate over pulleys. or sheaves,

37 mounted on shafts 38, which'shafts are supported on bearing brackets 39 (Figure 2). Additional sheaves or pulleys 40 are xed on shafts 41mounted in bearing brackets 42 (Figures 2 and 3).

Cables 44 have their ends attached to the peripheries of the sheaves 43 and bell cranks 45, pivoted at 46 have their outer ends connected to the cables 44.

Lugs 47 on the cylinder 28 (Figures 4 and 5) support the shafts 46 and rollers 48 mounted on pins 49 in the bell cranks 45 operate against cam elements 50 which are positioned on the ram 25, all as best shown in Figures l to 5 inclusive.

' The reference numeral 50a indicates a relief on a cam 50 (Figure 5), and this is defined by an incline 50b and includes a dwell ,or holding surface 50c.

Springs 51 are attached to the lower ends of the gates 31, as shown in Figure l, and sloping sides 52 mounted on hinges 53 are provided to form part of the hopper construction.

This hopper construction also includes end cheek plates 54 (Figures 2 and 3) provided with arcuate slots 54a. Angle brackets 55 are tted onto the hopper sides 52 and these include studs 55a which pass through the slots 54a and winged nuts 56 are tted onto the studs 55a, whereby the hinged hopper sides 52 allow material placed thereon to automatically slide under the ram. The sides can be adjustably Xed in position with respect to the cheek plates 54.

As the ram 25 and its connections, including the cams 50, moves up and down, therollers 48 on the bell-cranks will operate against the faces 50a and 50c of the cams 50, thereby moving the outer ends of the bell-cranks 45 in such a fashion that the cables 44 will move the sheaves 40--43 and the attached cables 36 over the pulleys 37 so as to accordingly and simultaneously move the gates 31 in a reverse vertical operation. In other words, when the ram 25 is moving downwardly, the gates 31 are moving upwardly and vice versa. This will automatically confine the material to be compressed between the gates 31 during the compressing and baling operation while at the same time allowing ready access to `the interior for placing material in the press when the ram 25 is in its uppermost position.

Grooves 57 are provided in the top surface of the base 12, all as best shown in Figures l and 3, and these grooves are for the insertion of baling wires or strips which can be inserted therein prior to charging of the press. In this manner a suitable bale may readily be formed after the material in the press has been com- -pressed into the desired minimum space, and this wired or strapped bale can then be readily removed from the press through the gates 1S.

It will be evident that the apparatus of this invention will provide a simple, convenient, readily operated and practically automatic mechanical device, which will compress all types of such material, including trash, refuse, tin cans and the like into a neat, easily handled unit. It will eliminate the need for incinerators, which contribute to a great degree to the impurity of air, and resultant smog in a community or area so affected will be reduced.

The invention will also provide a neat, useful and properly organized method for disposing of refuse, thereby improving the appearance of refuse storage areas around homes, restaurants, schools, factories and other commercial and non-commercial establishments, all of which include at one time or another the necessity of trash disposal.

The apparatus will materially reduce tire hazard and storage space for the refuse will be at a minimum. Considerable time in the disposal operations will also be saved.

The device may be made in practically anysize and can be used for baling paper, cotton, excelsor and all sorts of other'materials.

I am aware that many changes' may be made and numerous details of construction varied throughout a wide range without departing from the principles of this invention; and I, therefore,fdo not propose limiting the patent hereon otherwise than as necessitated by the prior art.

I claim as my invention:
